A Princeton grad built a $30 million AI detection business. Now he's selling it to Superhuman.

Edward Tian, a 26-year-old Princeton graduate, has sold his successful AI detection startup, GPTZero, to Superhuman for $30 million. Tian developed the company shortly after discovering the challenges of detecting AI-generated text, a problem that's increasingly relevant as AI tools proliferate. This acquisition highlights the growing market for AI authenticity tools, underscoring the demand to differentiate human-generated content from machine-created text in an era where AI is more accessible than ever. Superhuman's move signals a strategic investment in maintaining the integrity of digital communications.
